those that contain considerably more protein than is 

 found in carbonaceous feeds are called nitrogenous feeds. 

 They are called nitrogenous because nitrogen is the prin- 

 cipal distinguishing element of protein as compared to 

 the composition of carbohydrate. The latter is composed 

 of carbon, hydrogen and oxygen, while the former also 

 contains nitrogen and sometimes sulphur. Many nitrog- 

 enous feeds contain much more carbohydrate than pro- 

 tein.
